Three of the leading gear/technology companies for both musicians and consumers alike are partnering up with Guitar Center for an in-store appearance unlike any other. The "Metal Masters" will be making a stop at Guitar Center in Union Square (25 West 14th Street) on September 6, a day before their sold-out clinic at the Gramercy Theatre. The signing will take place from 1:00 p.m. to 3:00 p.m. and will include appearances by Philip Anselmo (PANTERA, DOWN), Kerry King (SLAYER), Dave Lombardo (SLAYER), Scott Ian (ANTHRAX), Charlie Benante (ANTHRAX), Frank Bello (ANTHRAX) and newly added masters Billy Sheehan (MR. BIG) and Gary Holt (EXODUS, SLAYER). There is a limit of one item signed per customer. There will be discounts on all Samson/Hartke/Zoom products and anyone who purchases one of their products will get moved to the front of the line. The Guitar Center in-store promises to be an event not to be missed.

If the still-circulating buzz from "Metal Masters 3" is any indication, "Metal Masters 4" will not disappoint anyone who is lucky enough to see it. "Metal Masters 3", which took place at the Key Club in Los Angeles, featured the "Metal Masters" demonstrating their personal techniques and styles used to create the music that millions bang their heads to every day. The highlight of the event came when vocalist and now returning "Metal Master" Philip Anselmo jumped onstage to perform SLAYER fan favorites "Angel Of Death" and "Raining Blood" before launching into five songs from the PANTERA classic album "Vulgar Display Of Power". Anselmo and the "Metal Masters" comprised of David Ellefson (MEGADETH), Chris Broderick (MEGADETH), Kerry King (SLAYER), Dave Lombardo (SLAYER), Charlie Benante (ANTHRAX), Frank Bello (ANTHRAX) and Mike Portnoy (ADRENALINE MOB, FLYING COLORS), blazed through "Mouth For War", "A New Level", "Walk", "Fucking Hostile" and "This Love". Geezer Butler, of the legendary BLACK SABBATH, joined all of the "Metal Masters" on stage for the finale of "Hole In The Sky".
